This data table provides a collection of information from peer-reviewed autism prevalence studies. Information reported from each study includes the autism prevalence estimate and additional study characteristics (e.g., case ascertainment and criteria). A PubMed search was conducted to identify studies published at any time through September 2020 using the search terms: autism (title/abstract) OR autistic (title/abstract) AND prevalence (title/abstract). Data were abstracted and included if the study fulfilled the following criteria: • The study was published in English; • The study produced at least one autism prevalence estimate; and • The study was population-based (any age range) within a defined geographic area.

Many neurodivergent (ND) young people will have negative experiences in childhood; autistic people are more likely to experience adverse childhood experiences (Hoover & Kaufman, 2018), such as bullying (Novin et al., 2019), and this has also been shown in those with ADHD (Schilpzand et al., 2018). It has been suggested that societal factors, such as stigma and discrimination (Han et al., 2022; Turnock et al., 2022), likely contribute to this risk. Different sensory and cognitive profiles may also contribute to vulnerability to negative experiences and trauma responses. ND people experience more mental health problems than their neurotypical peers; this has been shown for autistic (Kerns et al., 2020), ADHD (Brook et al., 2013) and dyslexic (Georgiou et al., 2024) young people. Recent work with autistic adults and children has shown that, after experiencing a trauma, severity of PTSD symptoms is higher than for non-autistic people (Quinton et al., 2024). Our unpublished findings in a longitudinal dataset of 1,506 young people show that autistic traits in childhood are associated with elevated likelihood of PTSD diagnosis at age 18 years (https://osf.io/uf9t7/). Trauma-related mental health remains under-researched in autistic young people and those with other forms of neurodivergence. Data from OxWell 2023 allows exploration of the trauma experiences of adolescents who self-identify as ND, compared to those who do not. Taking both dimensional and categorical approaches, this study aims to: 1. Assess if the adolescents who self-identify as ND are more likely to have had certain negative experiences than their neurotypical (NT). 2. Explore if gender, ethnicity, socio-economic status and year group are associated with negative experiences differently in ND versus NT young people. 3. In adolescents who have had negative experiences, compare the mental health of those who self-identify as ND vs those who do not. 4. Explore the relationship between negative experiences and mental health and assess if ND status has a moderating effect on these relationships. Although we cannot infer causal links between trauma experiences and mental health in the present cross-sectional data, understanding more about neurodivergent adolescents’ experience of trauma and mental health at a descriptive level still has important implications.
